UART Registers
4136B–USB–09/03
Example of computed value when X2 = 1, SMOD1 = 1, SPD = 1
Example of computed value when X2 = 0, SMOD1 = 0, SPD = 0
The baud rate generator can be used for mode 1 or 3 (refer to Figure 34.), but also for
mode 0 for UART, thanks to the bit SRC located in BDRCON register (Table 60.)
SADEN - Slave Address Mask Register for UART (B9h)
Reset Value = 0000 0000b
SADDR - Slave Address Register for UART (A9h)
Reset Value = 0000 0000b
SBUF - Serial Buffer Register for UART (99h)
Reset Value = XXXX XXXXb
